After 23 years in the House of Representatives, Colorado's Pat Schroeder says this term will be her last. Credited with pinning the "Teflon president" label on Ronald Reagan, Schroeder is the highest-ranking woman in Congress and the first to be appointed to the Armed Services (now National Security) committee. First elected to the House in 1972, Schroeder flirted with a presidential bid for three months in 1987 before dropping out. She becomes the latest in an increasing line of congressional incumbents who won't seek re-election next year. So far, seven Democrats and three Republicans have announced retirements from the House.
